Errors from subprocesses will display the current working directory.
Thanks Antti Kaihola.

Fixed issue #369 - compatibility with Subversion 1.7. Thanks Qiangning
Hong. Note that setuptools remains incompatible with Subversion 1.7; to
get the benefits of pip’s support you must use Distribute rather than
setuptools.

0.7

Fixed uninstallation on Windows

Added pip search command.

Tab-complete names of installed distributions for pip uninstall.

Support tab-completion when there is a global-option before the
subcommand.

Install header files in standard (scheme-default) location when installing
outside a virtualenv. Install them to a slightly more consistent
non-standard location inside a virtualenv (since the standard location is
a non-writable symlink to the global location).

pip now logs to a central location by default (instead of creating
pip-log.txt all over the place) and constantly overwrites the
file in question. On Unix and Mac OS X this is '$HOME/.pip/pip.log'
and on Windows it’s '%HOME%\\pip\\pip.log'. You are still able to
override this location with the $PIP_LOG_FILE environment variable.
For a complete (appended) logfile use the separate '--log' command line
option.

Fixed an issue with Git that left an editable packge as a checkout of a
remote branch, even if the default behaviour would have been fine, too.

Fixed installing from a Git tag with older versions of Git.

Expand “~” in logfile and download cache paths.

Speed up installing from Mercurial repositories by cloning without
updating the working copy multiple times.

Fixed problem with not being able to install private git repositories.

Make pip zip zip all its arguments, not just the first.

Fix some filename issues on Windows.

Allow the -i and --extra-index-url options in requirements
files.

Fix the way bundle components are unpacked and moved around, to make
bundles work.

Adds -s option to allow the access to the global site-packages if a
virtualenv is to be created.

Fixed support for Subversion 1.6.

0.3.1

Improved virtualenv restart and various path/cleanup problems on win32.

Fixed a regression with installing from svn repositories (when not
using -e).

Fixes when installing editable packages that put their source in a
subdirectory (like src/).

Improve pip -h

0.3

Added support for editable packages created from Git, Mercurial and Bazaar
repositories and ability to freeze them. Refactored support for version
control systems.

Do not use sys.exit() from inside the code, instead use a
return. This will make it easier to invoke programmatically.

Put the install record in Package.egg-info/installed-files.txt
(previously they went in
site-packages/install-record-Package.txt).

Fix a problem with pip freeze not including -e svn+ when an
svn structure is peculiar.

Allow pip -E to work with a virtualenv that uses a different
version of Python than the parent environment.

Fixed Win32 virtualenv (-E) option.

Search the links passed in with -f for packages.

Detect zip files, even when the file doesn’t have a .zip
extension and it is served with the wrong Content-Type.

Installing editable from existing source now works, like pip
install -e some/path/ will install the package in some/path/.
Most importantly, anything that package requires will also be
installed by pip.

Add a --path option to pip un/zip, so you can avoid zipping
files that are outside of where you expect.

Add --simulate option to pip zip.

0.2.1

Fixed small problem that prevented using pip.py without actually
installing pip.

Fixed --upgrade, which would download and appear to install
upgraded packages, but actually just reinstall the existing package.

Fixed Windows problem with putting the install record in the right
place, and generating the pip script with Setuptools.

Download links that include embedded spaces or other unsafe
characters (those characters get %-encoded).

Fixed use of URLs in requirement files, and problems with some blank
lines.

Turn some tar file errors into warnings.

0.2

Renamed to pip, and to install you now do pip install
PACKAGE

Added command pip zip PACKAGE and pip unzip PACKAGE. This
is particularly intended for Google App Engine to manage libraries
to stay under the 1000-file limit.

Some fixes to bundles, especially editable packages and when
creating a bundle using unnamed packages (like just an svn
repository without #egg=Package).

0.1.4

Added an option --install-option to pass options to pass
arguments to setup.py install

.svn/ directories are no longer included in bundles, as these
directories are specific to a version of svn – if you build a
bundle on a system with svn 1.5, you can’t use the checkout on a
system with svn 1.4. Instead a file svn-checkout.txt is
included that notes the original location and revision, and the
command you can use to turn it back into an svn checkout. (Probably
unpacking the bundle should, maybe optionally, recreate this
information – but that is not currently implemented, and it would
require network access.)

Avoid ambiguities over project name case, where for instance
MyPackage and mypackage would be considered different packages.
This in particular caused problems on Macs, where MyPackage/ and
mypackage/ are the same directory.

Added support for an environmental variable
$PIP_DOWNLOAD_CACHE which will cache package downloads, so
future installations won’t require large downloads. Network access
is still required, but just some downloads will be avoided when
using this.

0.1.3

Always use svn checkout (not export) so that
tag_svn_revision settings give the revision of the package.

Don’t update checkouts that came from .pybundle files.

0.1.2

Improve error text when there are errors fetching HTML pages when
seeking packages.

Improve bundles: include empty directories, make them work with
editable packages.

If you use -E env and the environment env/ doesn’t exist, a
new virtual environment will be created.

Fix dependency_links for finding packages.

0.1.1

Fixed a NameError exception when running pip outside of a
virtualenv environment.

Added HTTP proxy support (from Prabhu Ramachandran)

Fixed use of hashlib.md5 on python2.5+ (also from Prabhu
Ramachandran)
